(still reviewing/understanding)
This approach scans in 1 direction and "locally" - the decision on whether to do a parent frame fetch (or store the page locally) is made solely on a single child's relationship to it. If there are parent frames with many children references, they might still be tossed out by the single-child based criteria.
For now, I am asking to move deduplication into its own file, with a more apparent hook in chunk.go for deduplication. This would make it a little easier to compare strategies if a different one appears in the future.

The code flow is really complex. I would prefer simplifying (not a blocker though).
Please add more unit tests for the added functionality.

Adds disabled-by-default controls for memfile dedup fetch fragmentation. When enabled, dedup can promote the cheapest parent-hit pages into the current diff to keep distinct non-empty backing fetch windows under a configured budget, without ever storing empty pages.
Config keys:
maxFetchWindowsPerBlock,maxPromotedParentPagesPerBlock, andfetchRunWindowPages(all0= disabled/default window).
